APPARATUS FOR HEATING AND PITGHING BARRELS.

SPECIFICATION forming part of Letters Patent No. 460,291, datedSeptember 29, 1891.

Application filed June 30,

To all whoml it may concern: i

Be it known that I, FRIEDRICH JUNG, a subject of the King ofWiirtemberg, residing at Schorndorf, W'iirtemberg, in the Empire ofGermany, have invented a new and useful Improvement in Apparatus forHeating and Pitching Barrels, (for which I have obtained patent inGermany, No. 41,542, dated May 18, 1887,) of which the following is aspecification.

The object of my invention, as described below, is to burn outbeer-barrels with a direct flame and to remove the danger of explosions,which are still of frequent occurrencein pitching barrels. It is anotorious fact that the latter far more frequently occurs especiallywhen barrels are pitched by the application of hot air or steam thanwhen an open iiame or direct re is employed. The explosive gases aregenerated and the explosion is produced generally on account of a wantof atmospheric air in the barrel.

My novel apparatus is constructed as follows to obviate thesedisadvantages, and in the drawings, Figure l represents a verticalsection, Fig. 2 an elevation, and Fig. 8 a horizontal section, of thesame, while Fig. 4 represents the apparatus in use and on a reducedscale.

The apparatus consists of an outer tube A and an inner tube B, providedwith the small perforations a and b, respectively, the latter tube Bbeing lightly enveloped in some porous material d, such as asbestus,difficult of combustion, and absorbent or adapted to retain liquid orsemi-liquid fuel, such as boiling' resin.

To enable the smaller covered tube B to be easily inserted within theouter tube A, the latter is made in two parts or sections, connected bya hinge at a so as to be easily opened. An air-supply tube C is arrangedat the top of the tube A, which is somewhat tapering at its bottom tofacilitate its insertion into the barrel. One half of the tube A isfixed to the air-pipe C, while the other half may be secured thereto bythe screw c, and by loosening the said screw may be swung open. The tubeC is bent over at its top and connected with a ventilator or blower bymeans of a hemp or rubber hose, whereby the 1891. Serial No. 398,088.(No model.) Patented in Germany May 13, 1887, No. 41,542.

necessary air for combustion is conveyed to the burning apparatus andthe interior of the barrel is supplied with sufficient fresh air throughthe openings a2 of the tube A to prevent the formation of explosivegases.

rlhe apparatus operates as follows: The entire apparatus is dippedintoboiling resin, so as to till the middle tube B, and is then ignitedand introduced into the barrel through the bunghole. Air being now blowninto the same by the blower through air-pipe C, the resin is eX- pelledfrom the inner tube B and the flame intensied, so that the inner wallsof the barrel become heated and the old resin adhering to the same ismelted. rlhe old resin is then removed from the barrel, whereupon freshboiling resin is poured into the same and the barrel is rolled andturned.

What I claim, and desire to secure by Letters Patent, is-

l. A barrel-heater consisting' of a tube, as A, provided withperforations, as ctand a2, in combination with a tube, as B, providedwith perforations, as b, and arranged within the tube A, and a porousmaterial for retaining the fuel arranged in the space between the tubesA and B, substantially as set forth.

2.' A barrel heating and pitching apparatus consisting' of a tubeprovided with lateral perforations, in combination with a perforatedtube inclosed within the first tube and below the upper line ofperforations of the same, said inner tube being enveloped in asbestus,substantially as set forth.

3. A barrel heating and pitching apparatus consisting of an innerperforated tube lightly wound with material for retaining liquid fuel,in combination with a perforated outer tube made in two parts connectedbya hinge, substantially as set forth.

4. A barrel heating and pitching apparatus consisting of a tube, as A,provided with perforations, as o and a?, and formed in two parts hingedtogether, in combination with a pipe, as C, attached to one of theparts, and an inner foraminated tube, in material for retainingliquidfuel', substantially as set forth.

5. A barrel-heater consisting of the tubes A and B, provided with theperforations c',
